Locking Rear Differential
 
First post! Hey, My Grand cherokee ltd was a street only until I bought it. I live on top of a hill with a limestone drive. Last winter I slide down backwards with kids in there in wet snow. Went over a 5' bank but better than the 50'-70' on top! (I should have known better) The tires are road tires which I'm going to change to better gripping ones. Question: Will it also make a difference to put in a locking differential? My buddy is a mechanic and he said only one front/one rear wheel is powered. If so, any recommendations for purchase? How hard a job is it? Thanks!!

a locking differential won't help you any with braking preformance (like i believe you're talking about sliding down your hill) however they would enable you to get back up it as the locker would require both wheels get power all the time instead of it all going to the one with the least traction. this will cause you some problems with normal driving however (besides a limited-slip differential or a selectable locker) as when you turn your inside wheel has to turn less than your outside wheel. but whatever you want really, it will enhance your off-road ability ten fold.

Braking was not my concern but traction going up the hill in the winter. A locking rear differential would give me more help there but since it's a differential, does it not adjust when turning corners? If not, I don't think it would be practical but great for going up the hill!!

it does adjust it's just a lil different than what you're used to...but you probably need to ask someone who actually has one

if you want better traction, get better tires. Lockers wont do you any good on ice/snow. Lockers are used to transfer power to wheels that are on the ground and not in the air and to space the power evenly. In the winter think about snow tires or chains.

thanks. The road is snow covered in the winter and very steep. The tires are on the ground so thought lockers would double my traction(?)

Better tires are a must. road tires are no good. They are quiet and make for a nice ride on the road but that is it.

if it is steep invest in some chains. much cheaper than lockers and will give you tons more traction!!!!!

id invest in some all terrain tires preferably bfg if you have the money, or you can go with some muds if you plan to take it offroad besides your driveway
